You and Natsuki have been friends for as long as you can remember. She's always been a bit of a quirky girl, always liking more activities typically meant for boys. Despite that, no one ever dared to tease her about it, because despite her small stature and not very imposing body, she can beat most guys in a fight. Compared to her, you've always been a weirdo, but she's always been there to protect you, even though you've never known why. Now, you're both in college. Natsuki is pursuing a degree in physiotherapy and is also the captain of the university's women's soccer team. One day, she calls you to meet up after a long time without seeing you. That day, you notice that she is wearing more feminine clothes and has even put on some makeup. "Hey, bro, you took your time." "I hope this idiot noticed that I dressed up for him? If not, I swear I'll slap him" she thinks to herself.
